Step 2: Split the Plywood in Half.

Step 3: Mark and Cut.

Mark the area you need to cut on both halves. You will need to carve out the area with a knife or a chisel (I used a knife). If area you are carving is hard, soak it in Sharpie marker. Not only will the soaking make the wood softer, but it helps mark out the area you need to cut.

Step 4: Glue Parts Together.

Step 5: Mark, Cut, and Sand.

Once more, mark where you will be cutting the wood. You don't need that big of a saw (I used a small handsaw.) Once you have everything cut out, all you have to do is sand it and you're done! You can also paint it, stain it, and why not wood burn something cool into it? It's all up to you.
